In the Linux kernel, the following vulnerability has been resolved:
spmi: mediatek: Fix UAF on device remove
The pmif driver data that contains the clocks is allocated along with
spmi_controller.
On device remove, spmi_controller will be freed first, and then devres
, including the clocks, will be cleanup.
This leads to UAF because putting the clocks will access the clocks in
the pmif driver data, which is already freed along with spmi_controller.
This can be reproduced by enabling DEBUG_TEST_DRIVER_REMOVE and
building the kernel with KASAN.
Fix the UAF issue by using unmanaged clk_bulk_get() and putting the
clocks before freeing spmi_controller.
